The GSL2681 also features a number of advanced features, such as water rejection, palm rejection, and gloved hand support.

The GSL2681 is a QFN48 package IC and operates from a power supply voltage of 2.8V to 3.3V. It can support up to 10 touch points and has a maximum sampling rate of 100Hz. The GSL2681 also features a built-in I2C interface for communication with a host processor.

The GSL2681 is a popular choice for touch screen applications in a wide range of devices, including smartphones, tablets, laptops, all-in-one PCs, and digital signage. It is also used in a number of industrial and automotive applications.

Here is a more detailed description of some of the key features of the GSL2681:

• High sensitivity: The GSL2681 is highly sensitive to touch and can detect even the lightest touch. This makes it ideal for use in devices with touch screens that are used in a variety of environments, such as smartphones and tablets.
• Multi-touch support: The GSL2681 supports up to 10 touch points, making it ideal for use in devices with touch screens that are used for multi-touch gestures, such as zooming and panning.
• Gesture recognition: The GSL2681 supports a variety of gesture recognition features, such as swiping, tapping, and double-tapping. This makes it ideal for use in devices with touch screens that are used for gesture-based navigation.
• Water rejection: The GSL2681 features water rejection technology, which allows it to continue to operate even when the touch screen is wet. This makes it ideal for use in devices with touch screens that are used in outdoor or industrial environments.
• Palm rejection: The GSL2681 features palm rejection technology, which prevents the touch screen from registering accidental touches from the user's palm. This makes it ideal for use in devices with touch screens that are used for extended periods of time.
• Gloved hand support: The GSL2681 supports gloved hand operation, making it ideal for use in devices with touch screens that are used in cold environments or in environments where the user is required to wear gloves.

The GSL2681 is a powerful and versatile capacitive touch controller IC that is ideal for a wide range of applications. It is highly sensitive, supports multi-touch and gesture recognition, and features water rejection, palm rejection, and gloved hand support.

Here are some examples of devices that use the GSL2681:

• Smartphones
• Tablets
• Laptops
• All-in-one PCs
• Digital signage
• Industrial control panels
• Automotive infotainment systems
